Once dialysis is done for renal failure, whether it must be done for a long time is usually related to the nature of renal failure, acute renal failure may be off dialysis in the late stage, while chronic renal failure often requires long-term dialysis.
Chronic renal failure usually has serious electrolyte disorders, acid-base imbalance, accumulation of toxins in the body, manifested as azotemia, edema, hyperkalemia, metabolic acidosis, etc. At this time, because renal failure has not been able to recover, dialysis is often required, and generally should be regular and long-term dialysis after starting dialysis.
When acute renal failure, the renal function condition may be reversed, when the renal function gradually recovered, the patient can get out of dialysis.
It is recommended that patients with renal failure should go to the hospital in time, have regular checkups, and choose dialysis or other treatments to slow down the progress of the disease under the doctor’s advice.
